PATENT OFFICE.

RHODE ISLAND, ASSIGNOR TO SCHOT' BROTHERS, OF SAME PLACE.

BUTTON- To aZZ whom it may concern.-

, Be it known that I, HORACE THURSTON, of Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Buttonfllachines;

and I hereby declare that the following is a full, clear, and exact description of the same,

reference being had to the accompanying drawings, forming part of this specification.

This invention has reference to improvements in machines for uniting cloth with the metal shell and disk to form a cloth-covered button.

The object of this invention is to simplify the construction and cheapen this class of button-machines.

This invention consists in the peculiar and novel construction of the machine, by which the dies or formers can be operated to form the button and then placed into a presser to consolidate the same, as will be more fully set forth hereinafter.

Figure 1 is a section through the center of the two die-blocks, showing the followers 2 5 drawn out and the material for the button in place. Fig. 2 is a sectional view of the two die-blocks and the presser, showing the followers in the position occupied when the button 18 formed ready to consolidate the parts.

0 Fig. 3 is a sectional view of the button-inachine, showing the parts in their respective relations when the button is completed. Fig. at 1s a cross-section of the machine, taken on the line A B of Fig.

In the drawings, (3 indicates a block provided with the inner annular project-ion 7, and 8 a block having the outer annular flange 9, the projection 7 fitting into the recess within the flange 9. The block 6 has the central cylindrical opening 10, in which the die llslides. The lower end of the cylindrical opening has the annular conical enlargement 12. The die 11 is provided with the longitudinal groove 13, into which the end of the pin 14, secured in the block 6, enters and by which the die is held against rotation and the sliding motionis limited. The block 8 is provided with a central cylindrical opening of larger diameter than the opening 5o 10, coinciding with the largest diameter of MACHINE.

SPECIFICATION forming part of Letters Patent No. 443,417, dated December 23, 1890.

Application filed J 11y 1, 1890- $erialNo. 357,456. (No inodel.)

the annular conical enlargement 12. The die 15 slides in the cylindrical opening in the block 8, and is limited in its traverse movement and held against rotation by the longitudinal groove 13 and pin 14 in the same manner as is the die 11. The case or presser 16 is of general cylindrical outline, a part of the wall of the cylinder being removed, as is shown in Fig. 4, to permit the insertion of the blocks 6 and 8 with the dies 11 and 15. The case is provided with the circular bottom 17 and top 18, in the latter of which the screwspindle 19 is screw-threaded, the screw-spindle being provided with the handle 30. The die 11 is provided at its inner end with the cup 21 and the dished annular face 22, while the end of the die 15 may be straight, or, as

is shown in the drawings, slightly concave.

23 indicates a piece or disk of cloth; 24, a metal shell having an annular rim, and 25 a conical disk, these being the parts from which the button is formed.

I will now, to enable others to use my machine, more fully describe the operation of the same.

hen abutton is to be made, thetwo blocks 6 and 8 are separated. Into the cylindrical opening in the block 8 a disk of cloth 23 and the metal cap 24 are inserted, and into the cylindrical opening 10 of the block 6 the conical disk 25 is pushed, so as to rest against the annular face 22. The two blocks 6 and 8 are now placed together, as shown in Fig. 1. They may now be grasped by one hand, while with the fingers of the other hand, or in any 8 5 other convenient manner, the dies 11 and 15 are pushed into the position shown in Fig. 2, when the blocks and dies are placed into the presser, as shown in Fig. 2, and the screw is turned to force the dies against the button, as is shown in Fig. 3. On examining Fig. 2 it will be seen that the edges of the cloth 23 are gathered inward and that the disk 25 rests on the cloth. hen now pressure is exerted, the disk 25 and the cloth edges are pressed 5 into the metal cap 24, and the pressure being continued the beveled end 12 of the die 11 will bend the annular edge of the cap 24 and the cloth over the edge of the disk 25 and thus permanently secure all the parts toree gether, thnscnablingany unskilled person to a make their own buttons. 1

Havingthus described my invention l 1 claim as new and desire to seen re by Letters Patentl 1. The combination, in a buttolrniachino, t with the blocks 0 and 8, each provided with t a cylindrical opening and an annular ring constructed to hold the blocks in their predel termined axial relation, of the die 11 and the 1 die 15, each provided with a longitudinal groove, the pins 1i, secured in the blocks ti and 8, and an independent screw-press constructed to receive the blocks and dies and consolidate the material to form the button, as described. i

L. The combination, with the bioek t5, pro- 1 vided with the cylindrical hole 10, the bevoled edge 12, the pin 14, andthe projection 7, ot the block 8, provided with the flange 9and pin 14:, the dies Ilt and 15, having theirinner ends formed to receive the button material and compress the same to form the button, and each provided with the groove 13, and the presser-ease 16, provided with the bottom 17, top 18, and screw-spindle 1.), having the handle 20, the case being open on one side to 1 receive the blocks and dies, as described.
